This landscaping study investigates the electrical connection infrastructure of wave farms. It aims to identify cost reduction opportunities specific to the electrical connection infrastructure, whereby cost efficiencies made in the supporting infrastructures would in turn improve the Levelised Cost of Energy (LCOE) for wave farms overall.
Modelling and Validation of Power Take Off Systems for Control Development
Wave Energy Scotland Ltd
Following on from the delivery of the "Control Requirements for Wave Energy Converters" Landscaping Study, WES has identified the need for guidance on the specification and interfacing of models and simulations of Wave Energy Converters (WEC), and Power Take Off (PTO) systems in particular, for use in control development and performance assessment work.
The aim of this report is to both provide a condensed background description of Power Take Off (PTO) modelling requirements and the specifications required by control developers to use in the development of practically realisable controllers; and to provide distilled guidance to control developers on PTO specifications and how to include this required functionality in their models, allowing them to characterise performance with respect to them. This will lead to realistic results by being able to model realistic PTOs, and specification feedback can be offered to PTO developers.
